I like elements of the forest, such as the river and trees, but I’ve decided I’m not very fond of this particular set. The grass in particular just doesn’t have the dimension or quality I’m lookng for. Thanks for everyone for the advice. =-)
If you need something in the nearer term, for grass, you could try Predatron’s Grass, or, if you’re looking for something that will work in medium distance renders, First Bastion’s Hilly Surround. No trees in either, but depending on what you need to do, you could get some of Merlin’s trees for that as well.
Using a lot of Predatron’s Grass WILL slow down your system a bit. And even though I ubersurfaced it within an inch of its life, it does take ages to render.
